United Productions of America, Howard T. Batchelder
Summary:
Through animation, the film compares and contrasts the "assembly line" kind of educational process with one that is tailored to meet young people's needs. Shows how in the former little or no consideration is given to individual needs, whereas in the latter a decentralized educational system can fit the curriculum to local community setups.

Summary:
Delineates interesting facets of the development of our decimal system. Compares the additive, subtractive, multiplicative, and positional notation aspects of the Chinese, Babylonian, Egyptian, and Hindu-Arabic systems. Uses models to explain concepts which lead to greater understanding of base 10 systems.
This film traces the historical development of our present decimal system--the Hindu-Arabic system of numeration. The meaning and importance of base ten, place value, grouping, numerals, and expanded notation are carefully described.
Portrays the role of developmental genetics in dealing with ways phenotypes come into being through the action of genes. Presents a complete discussion of the Creeper domestic fowl--its genetic basis, morphology, embryological history, and the experimental work that led to an understanding of how this gene affects early development to produce the morphological features seen as the outcome of the developmental process. Lecture given by Dr. L. C. Dunn.
Describes the ways in which genes produce phenotypic differences by acting very early in embryonic development. Shows that this action may take place at a distance through chemical messengers (pituitary dwarfism in the house mouse, lethal giant larva in Drosophila), or it may involve tissue induction systems (Brachyury and taillessness in the house mouse). Discusses the development of eye color in Drosophila as a model of how each of the steps in a chain of chemical processes leading to development is under genic control. Lecture given by Dr. L. C. Dunn.
Follows a car thief, played by an actor, as he steals cars and offers recommendations to the spectator on how to protect their car. Includes footage of various people looking through documents, reenactments of cars being stolen and owners being upset when they realize what's happened, the process of car owner alerting police to theft, being interviewed by police, and police searching for the car; car being broken apart at chop shop; tips on what car owners can do to reduce the chances that their car will be stolen; women looking at microfilm machines; shot in and around Indianapolis; ends with car their behind bars.

Summary:
Uses animation to show the mechanical and muscular processes involved in the digestion of food. Includes the absorption of digested food, water, and salts into the blood and the function of the liver.

Summary:
Uses animation to demonstrate the chemical processes of digestion. Shows the chemical breakdown of foods, the structure and functions of the glands involved, the absorption of digested foods, and the distribution and storage of food in the body.
